Owners of the Hard Rock Hotel & Casino in Las Vegas say a federal lawsuit from the owners of the Hard Rock Cafe chain over their shared moniker is without merit.

Morgans Hotel Group Co. spokeswoman Jennifer Foley on Friday declined further comment on the restaurant chain's complaint, which argues that the hotel's party image hurts the name and justifies ending a 14-year-old licensing agreement.

Cable reality show "Rehab: Party at the Hard Rock Hotel" on truTV is one of several examples of what puts the brand in a bad light, Orlando-based Hard Rock Cafe International Inc. said in the lawsuit filed Tuesday in New York.

The restaurant chain says the hotel-casino goes too far, with "Rehab" depicting unprofessional, abusive staff members who are incompetent and offensive to the public and normal Hard Rock Cafe customers.
